2002 Rousch Stage 1???

Well, since there is not a Rousch category post, this question is for anyone to answer. I'm looking for advice about whether a 2002 Rousch Stage 1 with only 6K miles would be a good deal for $15,900? I would get it from a dealer here in Illinois- probably get the extended warranty, even though it has about a year and a half coverage under factory. Does anyone have any advice about this possible purchase??
